LILYGO® T-Deck Portable Microcontroller Programmer LoRa 915 MHz H642


T-Deck is a pocket-sized gadget with a 2.8-inch, 320 x 240 pixel IPS LCD display, a mini keyboard, and an ESP32 dual-core processor. It is not a smartphone though it looks like one- but you can use your programming knowledge to turn it into a standalone messaging device, or use with coding software for programming.
